poct is an abbreviation of the English point-of-care testing, translated to instant testing, refers to the clinical testing and bedside testing next to the patient, is a sampling site immediately analyzed, eliminating the complex processing of specimens in the laboratory test, a new method to quickly get test results.
POCT meaning can be understood from two aspects: spatially, in the patient's side of the test, that is, "bedside test"; time, can be carried out "instant test".
Second, poct test features what
In recent years, due to the development of today's high-tech and medical science progress, as well as efficient and fast-paced way of working, so that the experimental instrumentation miniaturization, operational simplicity, the report of the results of the instantaneous POCT more and more favored by the people, poct test features are:
1, fast!
The main purpose of POCT is to get the experimental results faster, poct test is very fast, for example, for the diagnosis of AMI patients, if the clinical manifestations of highly suspicious electrocardiogram performance is not decisive diagnostic significance, the myocardial injury markers cTnI bedside diagnostic reagents can make the diagnosis of such acute patients and the determination of the therapeutic program has become easier and more accurate, the whole process takes only 15 minutes. The entire procedure takes only 15 minutes.
2, simple to use
Operation is simple, easy to use is another feature of POCT, POCT by virtue of its ease of use has become part of the diagnostic system; POCT takes on the functions of the laboratory but does not require the traditional hospital laboratory equipment. POCT can be done in the doctor's clinic can also be done in the car. POCT can be performed in the doctor's office as well as in a moving car, regardless of time and place.
3, saving the overall cost
From the "individual test cost" considerations, POCT is relatively high; but in many cases, the application of POCT can not only improve the experimental results and can reduce the occupation of resources, the patient's hospitalization time, sampling time, the occupation of health care personnel time.
Three, what are the items of POCT test
In the clinical field, POCT can detect a lot of items, including:
1, cardiac markers
POCT can detect a variety of cardiac markers, such as troponin (cTn), myoglobin (MY0), creatine kinase isoform (CK -MB), B-type brain natriuretic peptide (BNP), N-terminal pro-brain natriuretic peptide (NTerminalPronatriureticPeptide, NT-ProBNP), and ultrasensitive C-reactive protein (hsCRP).
2. Clinical Chemistry
The application scope of POCT in clinical chemistry testing basically includes the items that can be detected by conventional biochemical analyzers, such as electrolytes, liver function, renal function, lipids, and blood gases.
3, anticoagulation therapy
Conventional coagulation function indicators such as PT, APTT, Fib, INR, platelet function, D dimer can be detected using POCT equipment.
4, routine clinical testing
In the clinical field, POCT can be used for urine dry chemical examination, fecal occult blood test, routine blood test, etc..
5, microbiology
POCT in microbiology testing is mainly used for rapid detection of certain pathogenic bacteria.
6, home health care
After a simple training of non-medical professionals to complete the POCT operation, such as diabetic patients through the palm glucose meter at home to measure their own blood glucose concentration, oral anticoagulant patients self-check the INR, women of childbearing age through simple test strips self-check urinary hCG, LH, to predict ovulation, and so on.
